Application fled September 12, 1928, Serial No. 805,595,

This invention relates to an apparatus for the production at high speed of white or colgre paper glazed and/or colored on one As is well known in the paper making art,

the glazing of paper involves its passage with a determmate content of water over a drycylinder having a polished surface. Heretofore serious drawbackswere met with in the glazing of paper due-'to the circumstance that the water content of the paper varies considerably with its thickness at the moment of its passage over the final drying cylinder. I

is thin, it frequently happens If the paper that the water content is msufiicient, whereas if the paper-is relatively thick, the content of water is frequently too great to permit of satisfactory glazing. These drawbacks are avoided according to the invention by efiecting the drying of the paper in a continuous machine irrespective of the glazing (gieration and then distributing the paper in front of the fina drying cylinder or the drying cylinder having a olishedsurfacea certain uantity of water 'buted uniformly over e breadth of the web in such manner as to ensure the presence of the exact quantity of water necespractice, the water' employed for moistening the paper may be clear water or it may be water with the addition of colloidal matter adapted to enhance the glazing. Further if added to the water there may be obtained pa r glazed and in two colthat is of di erent colors on. the two faces, and adapted to take the place of bichrome paper heretofore produced by securing together b means of adhesive two sheets of difierent co ors or by application of a layer of color to thepaper and its passage through amachme emplo ed for the manufacture of colored paper. enerally, the invention permits of replacing papers produced by employment of separate machines independent of the continuous machine. An important condition in the manufactur of glazed paper or of bichrome paper glazed or not onone face being to obtain uniform aruaana-rns roa THE rnonnc'rron or rarna emznn AND/OR cononnn on our. racn and in Belgium September 15, 1987.

distribution of the water or of the colorin liquid employed on the face to be treate use is made of a distributor (for the" clear water orcoloring liquid) connected to a float regulator and receiving filtered or purified liquid from one or several reservoirs so as to ensure distribution always under thesame head. In the manufacture of bichrome paper use is preferably made of' two reser- VOllS provided with agitators for eifecting solution of the coloring matter, these reservoirs being arranged in'series and adapted to be isolated from or put in communication with. one another in order to permit the prepara-' tion of a certain quantity of coloring solution durmg the use of With the above mentioned objects in view as i another part of this soluti on or of a solution of difierent'color.

the invention essentially consists in the special arrangements .and combinations of parts hereinafter full described and. pointed out in the appende claims.

On the annexed drawings:

Fig. 1 is a view in elevationshowing diagrammatically the assembly of the apparatus as adapted to be utilized for glazing paper with the use of clear water.

Fig. 2 is a corresponding plan view.

Figs. 3 andd show modifications of this arrangement, employed in the manufacture of bichrome paper or of paper to be glazed by means of water containing colloidal matter or otherwise prepared. Figs. 5 and 6 show two alternative forms of the device for ensuring distribution of the water or liquid over the paper sheet.

F1 7 shows an alternative form especially fort e making of bichromepaper.

In the exampleshown in Figs.'1 and 2, 1 denotes a reservoir adaptedto contain clear water. This reservoir which is provided with a drain connection 2 with cock 3, feeds by way of a pipe 4 fitted with a regulating cock 5 and a removable sieve 6 a regulator 7 which determines the depth of the water utilized for moistening the paper. With this object the water contained in-the reservoir 1 flows into the regulator 7 by way of an o ening controlled by a valve 8 actuated by a nected to a float 10 soas to maintain a conever 9 conas usual over a guide roller 16 whence it is re-' turned to the paper machine in the usual way, whilst the paper passes first under a distributmg roller 17 and then between the pressure roller 19 and the drying cylinder 18' before turning around the latter. In operation, the water flowing from the reservoir 1. to the regulator 7 passes by way of the distributor tu e 13 disposed transversely of the felt above the pa er. This distributing tube 13 being pierce with a large number of holes, the water is distributed over the pa r so as to form a p901 at 20 in front of t e roller or other distributing member 17. The water is thus uniformly distributed over the surface of the paper which immediately thereafter passes into contact with the olished surface of the dr ing cylinder 18 o the paper machine. ith this water added the paper is brought to the proper degree of humidity and 1s glazed at high speed in the paper machine, f bichrome paper is to be produced there are incorporated in the installation evices shown in Figs. 3 and 4' whereby coloring liquid isintroduced into the reservoir 1. As shown, there is located at a higher level than the reservoir 1 a second reservoir 21 provided with an agitator22 rotated through the intermediary of gearing 23.

This reservoir 21 is fitted with a thermometer 24 and receives in its interior a steam coil.

25 fitted with a cock 26. 27 denotes a draining pipe connected to the bottom of the reservoir 21, and 28 a removable sieve for retaining impurities. The liquid or bath prepared in the-reservoir 21 passes by way of the'pipe 29, the delivery of which is controlled by a cock 30, to the reservoir 1 which may also be provided with an a itator 31 rotated through the intermediary 0% coloring liquid may be prepared in the reser- You 21 while the coloring liquid previousl perspared and contained in the reservoir 1 1s mg utilized in the manufacture of bichrome papgfi. ether the apparatus is utilized exclusively for the I lazing of paper or for the manufactureof ichrome paper, the distribution of the liquid on the sheet is effected by the distribution regulator 7 co-operating with the perforated tube 13 and withthe'distributthe l or 100 20 which is essential in order to o tain a umform distribution on the surmay also be used if size or colloidal matter is v to be added to the water.

gearing 32. In this case mg roller 17 which ensures the formation of As is understood a like arrnt may be applied to other drying cylinders of the machlne, and in a given case the roller 17 may cooperatewith one or two cylinders in relief not shown so as to apply different colors and designs to the paper.

The tube 13 and the roller 17 are preferably mounted so as to be movable at will vertically or laterally by means of adjustable articulated sup orts.

For the pe orated tube 13 there may be substituted a distributing device of other type suitable for the class of paper to be produced. For example, for thin aper the perforated tube 13 may be replaced by a channel 33 of V-section as shown in Fig. 5, the lower edges of which channel may be br'oughttogether by adjustment of screws 34 so as to nip a wick offelt 35 which rubs on the paper over its width. The water whether colored or not, is delivered in the form of a regulated jet into the channel 33, prises through the wick and soaks the paper over its surface.

Fig. 6 shows a further modification of the distributing device in which a felt wick 35 is nipped at one end between the tube 13 for delivery of the liquid and a round bar 36 held against the perforated tube 13 by pieces 37 fitted with screws 38. The wic 35 rubbing at its' other end over the piper soaks it with liquidreceived from the tu 13.

Whatever arrangement of distributor be adopted, the liquid "is distributed in a sufiicientquantity to form the ]pool of liquid already mentioned at the re er 17 which distributes it uniformly over the surface of the paper in the course of manufacture.

As shown in Fig. 7 it may be useful in some cases to make use of two rollers 17 and 17 carried by a fulcrumed support whereby the may be raised or, lowered separately or rought nearer to or spaced apart from each other at will according to the necessities of manufacture in order to obtain the best distribution of the coloring substance.

The rubbing of the paper may cause this second roller 17 to rotate in the same direc- -tion as the roller 17. It may however be rotated in an inverted direction by means of a crossed cord passing on two little ooved pulleys mounted on one end of the axis of the rollers.

n this case the excess of colo sub-- stance brought to the roller .17 falls on both sides of the paper sheet and is gathered into a little-reservoir whence it is extracted b a little pump or other mechanical means whlch returns it automatically to the reservoir 21. The roller 17' then gives rise to theformation of a light liquid 111301 or loop 20 and equalizes in a thoroug y perfect manner, the distribution of the coloring substance on the whole width of the sheet of paper.

The rollers 17'and 17' may eventually be replaced by a scraper in polished glass on 'a coloring solution arran ed contained names:
